{"title":"Movements","description":"\u003cp\u003eEvery automatic build in the catalogue runs on a Seiko (TMI) NH movement, and this is where they live. NH35 for date builds — window at 3 o'clock or 6 — NH36 for day-date, NH38 for open-heart dials, the skeletonised NH72, and the NH34 GMT with its fourth hand for a second timezone. Black and white date-wheel versions match your dial, and the 4 o'clock crown NH36 serves cases with the crown at 4. Stems and dial holding spacers live here too.
